Ecteinascidia
Ecteinascidia is a genus of colonial tunicates, commonly known as sea squirts, found in marine environments worldwide. These filter feeders are known for their distinctive bright orange or red color, often found growing in clusters on rocks, piers, and other submerged surfaces.
Characteristics
Members of the genus Ecteinascidia are characterized by their vase-shaped, colonial structure. They are composed of numerous zooids, which are individual organisms within the colony. The zooids are connected by a common tunic, which provides structural support and protection. Each zooid has a siphonal opening for water intake and another for water expulsion, allowing them to filter food particles from the water. Ecteinascidia species are hermaphrodites, meaning they possess both male and female reproductive organs.
Environments
Ecteinascidia species are found in a wide variety of marine habitats, including rocky shores, coral reefs, and mangroves. They are particularly common in tropical and subtropical regions. These tunicates prefer areas with moderate currents and ample food sources.
